TVISTKNG AND WINDNG MACHINE.

Application led June l, 1920.

- lowing is a iull. clear. concise. and exact description, referencebeing had to the accompanying drawings. forming a part oll thisspecilication.

My invention relates to machines for twisting and winding silk, yarn,thread, cord and the like.

ln the manufacture ot various fabric articles it has been found that thebest results are obtained when the machines are supplied with thedesired silk or yarn from y conical rolls or cops of a particularstructure. rlhese rolls or cops are built up of a single continuousstrand wound in such manner to form in ellect a spiral wrapping of layerupon layer of the material.y the stra-nds of eac-l1 layer being inclinedin a direction opposite to those in a preceding layer. A cop or rollbuilt up in this manner retains its shape and insures at'ree and easyunwrapping of 'the material upon feeding ol the strands therefrom.llllachincs have been built for making up ay roll or cop of thischaracter in a satisfactory manner.

ln order to obtain a. strand of silk or yarn of sufficient coarsenessfor certain purposes it becomes necessary to imite two or more finerstrands by a twisting operation. Various types of machines have beenpro'- vided for performing this function b v twist-4 ing the severalfiner strands. together' and winding the resulting coarse." strand upona spool or bobbin. However. in order to wind this coarser strand into aroll or cop of the character above described it has been necessary totransfer the ordinary spool "or bobbin upon which the twisted strand iswound to a machine especially designed t'or winding the same into aconical roll. Thus at the present state of the art the formation of aconical roll oi silk` thread. yarn or the like of the desired coarsenesshas required two separate and distinct machines.

rl`he primary aim of my invention is the provision ot' a machine ofsimple construction which combines in one machine the functions of twomachines of the prior art,

i. e.. which twists the several lfiner strands into a strand oi thedesired coarseness and then winds the resulting coarser strand into aconical roll of the desired character. Thus not only is one machineavoided, but the intermediate steps-of winding onto and winding from anintermediate series of spools r bobbing is avoided as well. The savingof time` labor and'expense and the consequent eiiiciency of such a.machine is obvious.

A. further object et' my invention is the provision of a. twistingmechanism adapted for embodiment in winding machines now in use toconvert the same into combined twisting and winding machines. Theexpensive replacement of machines is thereby reduced.

A still further object of my invention is the provision of means forautomatically stopping the winding operation when the roll has reached apredetermined size.

Another objectis the provision of means for'autonnitically stopping thewinding and twisting operations upon the breakage or rupture of any oneof the several individual strands.

Other objcctsand advantageous features will appeal' from. the 'followingdetail description'and the claims. taken with an in spection of theaccompanying drawings. in which:

Figure 1 is a side elevational view partly in section of a twisting andwinding machine embodying the features of my invention;

Figure 2 is an enlarged fragmentary front elevational view partly insection of the machine illustrated in Figure l; and

Figure il isa horizontal sectional view taken substantially on the line3--3 of Figure Q..

The machine illustrated in the d awings includes a rotatable twisterhead 10 adapted to carry a plurality of spools 11, of silk, yarn. cord.thread or the like and a winding mechanism l2 having a rotatable conicalmandrel 13 for drawing the strands through the machine.

The winding mechanism may be of any approved construction` but in thepresent instance is of a well known type. The mandrel lll is secured toa shaft Il journaled preferably in the top of the machine. cone clutchelement 15 is fixed to the other end of the shaft i4 and cooperates witha ist movable clutch element 16 loosely mounted on the shaft. The outercylindrical surface of the clutch element 16 is preferably fashioned toreceive a driving belt 17 fromv 18 having oppositely beveled edges 19and 20 whereby the clutch element 16 is moved into and ont of engagementwth its co-operating clutch element 15 by means of cam fingers 21 and 22carried and actuated by a rock shaft 23. Finger 21 is engageable withthe beveled'snrlace 19 to move the disk 18 and consequently the clutchelement 16 to the right to close or eil'ect engagement between theclutch elements 15 and 16 while the linger 22 is engageable with thebeveled surface 2O to open the clutch or disengage the clutch elements15 and 16.

The position ot' the rock shaft 23 is controlled by a handle 24pivotally secured as shown at 25 to the hub 2G of a rock arm 2T. The arm2?'. carrying the hub 26. is fixed to the rock shaft 23. A tensionspring 28 (Figure 2) connected between an arm 29 l of tie roch arm 2Tand the frame 5 of the machine tends at all times to'rock the arm 27 andshaft 23 in such direction as to open or disengage the clutch. lll/henthe shaft 23 is rocked in the other direction by the manipulation ot'the handle'24 the clutch is closed or engaged and the mandrel 13 isdriven at a speed corresponding to the speedlof rof tation of the clutchelement '16.

Another arm 30 ot' the rock arm 2T car ries a hook or catch 31 for-o-opcration with a corresponding hook or catch 32 carried by a latchlever 33. The latch lever Btl is mounted upon a fixed pivot 34. When inits lowermost position, as illustrated in Fignre 2, the hook 32 is insuch position as to interlock with the hook 31 upon rocking the arm 27through the handle 24 to move the clutch element 16 into engagement withthe clutch element 15. The clutch is thus locked in closed posit-ionupon manually closing the same untilthe latchlever 33 has been raised orswung in a counter clockwise direction about its pivot 34. The hitchlever may be raised manually or by automatic trip mechanism such as Willbe later explained, in order to bring the winding mechanism to rest. Y

During the rotation of the conical mandrel 1? the twisted strand ofmaterial is diagonally wrapped thereabout in such manner as to build upa tight conical ball or roll thereon. This is accomplished by-causingthe strand to pass through a reciprocating or traverse guide thattravels back and forth lengthwise along thc mandrel. 'lhis guideincludes an cyc 35 that bears lightly against the roll 3G ot' thcmaterial. The eye 35, which eye is lierforatwl to permit ot the passageof the strand therethrough, car- 1 ,enana/i ried by the npturned end 3Tof a reciprocal rod 38. llod 38 is slidably mounted in a guidcway Si)toi-ined in a pivotcd arm Lil) and is provided witha guide finger orprong 11 co-operating with'thc upper edge ot an upright plate member i2fixed to the arm 40, The arm l!) is provided with an cn- -iargement 43reciprocably mounted in a lixed guide el and actuated by a cam plate tl.The eye 235 is reciprocated through a pin 15 depending from theenlargement l-l' which pin 4,5 is adapted for co-operation with a groove46 formed in the cam plate 8.

The cam plate 8 is mounted upon and driven by a shaft 1i' operativelyconnected with the shaft 11 in any suitable or preferred manner such asthrough thc pulleys 48 and li). belt 50, stub shai't 51 and gears 52 and53. The arm Lil) is loosely mounted upon the Jforwardly extending endot' the shaft #1T and is provided with a weight 51 for maintaining theeye 35 in light engagement with the roll ot' material *being wound onthe mandrel 13. Ot course. the eye 35 may be otherwise maintained inproper engagement with the roll ot' material as for example by means ota suitable spring.

lt will now be apparent that rotation of the cam plate 45 causes areciprocation of the eye 35 longitudinally of the mandrel 13 in suchmanner that the twisted strand is wound into a roll of the desiredconical Jf'orm. As hereinl'iet'ore pointed out, thc cam 'the rolln hasassumed a predetermined diameter, or in other words when a predeterminedlength of strand has been wound. This is accomplished by the use of acam block. 55 adjustably mounted on the latch lever 33, as by means of asuitable set screw 56 or the like. The block 55 is provided with a camsurface 57 for co-operation with a cam surface 58 with which the arm 40is provided (See Figure 2). When the dameter ot' the roll ot' materialupon the-mandrel 13 has increased sulhciently to move the :arm 40 tosuch position .as to causeeir gaglemcnt oi the surface 58 with the sur-Jtace 5T the latchv lever 33 is raised or swung about its pivot 34disengaging the catches 31 and 32 and thereby releasing the rock arm 27.rlhis arm 27 is thereupon swung by the spring 28 in a counter clockwise,direction litigare 2) about the L Xs 0f the finances or disk 62being-fixed upon the upright or vertical shaft 64 the lowerend ot' whichshaft is slidably mounted in a bearing.

bracket 71 suitably secured at its inner end to the frame 5pt themachine. it vwill -be apparent that upon enga-ging the under surface ofthe base place 62 further saving-A ing ot' the brake arm 6() about itspivot will move the shaft 64 axially upwardly. vrl`his upward movementof the plate 62, which disengages the external cone clutch element 68carried thereby from the internal cooperating driving clutch element 69loosely` mounted upon the shattt is limited by a prong or stop 72carried by the bracket member '71. 'lhus not only is the driving clutchfor the plate 62 disengaged, but the plate is clamped between the stop72 and the brake arm 60 and positively brought to rest. 'lhe peripheralsurface ofthe driving clutch element Gli is fashioned to receive adriving belt 73 through which the twisting mechanism receives its powerwhen the clutch elements 68 and 69 are in engagement as shown,

Fixed upon the shaft 6e above the spools 11 is a guide carrying member65 above which guide carrying member another guiding mechanism 66 isfixed upon the shat't 64. Means associated with the guiding mecha- .nism66 provides for automatically stopping nut '78.

The strands 74`ot' the yarn. silk or the like. as the case may be, uponbeing drawn Vfrom the spools l1 by the rotatable mandrel 13 of thewinding mechanism are guided independently upwardly through the guidingmechanism 66 and thence as a single coarscl strand 75 between a pair 'otguide disks 77. the friction of which. upon the strand 7:3` may beadjusted through a spring 76 and By reason oi the rotation of theguiding mechanisms 65 and G6 through which the strands are .guidedindependently and the fixed grasping or holding cli'ect ot the disks 77.it will be oncc be apparent that the finer strands will be effectivelytwisted into a coarser strand and then 'fed on vand consequently thecontrol rod 85.

The guidingr mechanism 66 includes a guide member carrying frame 8()secured through a suitable arm or bracket to the frame of the machineand a guiding spider 8l to each of the radiating arms of which adetector 82 is pivoted; 'lhese detectors 82 are retained in the positionshown in' full'lines in Figure 2 by engagementot' the bent or hookedwire fingers 83 thereof with the strands 74 extending up through theguiding mechanism, but are so counterweighted or pivoted as to drop orswing downwardly about their pivotal mounting upon disengagement of thestrand 74 `from the finger 83. 'l`hus it will be apparent that uponrupture or breakage ot either of the strands 74 the (,letector 82associated therewith will drop. and by reason of the rotation of thespider 81 carrying the same, will be swung outwardly by the centrifugalaction into substantially the position shown in dotted lines in vFigure2. Rotation ot the guiding vmechanisun with the detector in Suchposition will cause the detector to engage a downwardly extendingcontrol rod 85, moving the lower end ol this rod (Figure 3) from thet'ull to'lthedotted line position. The upper or opposite end of the rod85 is operatively connected with the latch A clockwise direction "by thespring 28 disen-` gaginghtheyclutch 'elements' 15 and 16. the clutchelements 68 and 69, and braking the twisting m'edhanislnagainst furtherrotation.

Upon ,disengagin'g the latch lever`33 the control rod R5 is returnedtoits normal or full line position by means of a spring 86 connected atits opposite ends with the end 97 of the rod S5 and a relativelystationary member respectively; such as. for example. the vtrame 5 ot'the machine. The end 87 is guided and limited in its movement by meansot' a suitable guide member 88 mounted upon the traine 5. llpongathering up the broken strand the detector associated therewith isarranged in the position shown in t'ull lines and the arm 27 is rockedagainst the tension of the spring 28 and locked in the position shown in-tull'lines by engage.. ment of the catches or hooks 3l and 32. Suchrocking of the arm 27 throws the clutches lov-1G and (ld-(Sil intoengagement and rcleases the brake arm (lll.
